I halfway agree with you. The comments underlying advice isn't that awful. But he really shot himself in the foot with the wording, and so I don't think it's weird that people take issue with the wording.
As I pointed out in another comment, he could've just argued for approaching people without expectations and intending it to go anywhere and suggested that a way of doing that is to approach people you're not attracted to.
In other words, make it about your intent and preference rather than about ranking women by appearance.
The reason why I suggest these co-workers approach ugos/low-mids: They tell me that they are too nervous to approach women "on their level" (whatever that means). (1) Most people are more comfortable to speak to strangers that they do not find (particularly) attractive. (2) Who knows... maybe that ugo/low-mid suddenly becomes a lot more attractive when you see their personality. Maybe they are funny, unusually kind/friendly/intelligent, or adventurous.
The Red Pill movement is about social manipulation to sleep with as many women as possible or have an endless string of situationships. My advice aims to help them to learn to meet strangers... and maybe spark a romantic connection. It is exactly how I dated my younger days... long before dating apps (when it was less brutal).
Again, my issue wasn't so much about your recommendation, but about how you presented it. As you can see in the responses, the way you worded it drew attention away from the advice and to that.
